Yes, it's the great time to buy up now because than all the altcoins will skyrocket again! As for which ones i recommend AION, REBL, EBTCH. All of them are really low right now and are undervalued. Time to get in it is right now!
I completely agree with you - now is a very good time to buy many coins. Except for those you listed, I recommend buying a ripple, Tron, Iota. I'm sure they will show excellent growth.
